I have multiple checkboxes in a form that need to be sent when submitted.  Right now when I submit the form the value I get for my checkbox group is "Array".  I know I need to convert to a string, I'm just unfamiliar with PHP.  Any help would be appreciated - code is posted below.
<?php
if(isset($_POST['Submit'])) {

$cname=$_POST['cname'];
$cnumber=$_POST['cnumber'];
$btime=$_POST['btime'];
$group1=$_POST['group1'];
$group2=$_POST['group2'];
$caddress=$_POST['caddress'];
$agent=$_POST['agent'];


$to="me@email.com";
$subject="Form Submission";
$from="email.com";
$data="Submission Form"."\n"
		."Customer Name : ".$cname."\n"
		."Customer Number : ".$cnumber."\n"
		."Best Time : ".$btime."\n"
		."AM or PM : ".$group1."\n"
		."Customer Address : ".$caddress."\n"
		."Agent : ".$agent."\n"
		."Insurance Type : ".$group2."\n";
		
mail($to,$subject,$data,"FROM : $from");
}
?>

Open in new window

<label>Homeowners Insurance </label><input name="group2[]" type="checkbox" value="Homeowners Insurance">&nbsp;&nbsp;&nbsp;<label>Auto Insurance </label><input name="group2[]" type="checkbox" value="Auto Insurance">&nbsp;&nbsp;&nbsp;<label>Life Insurance </label><input name="group2[]" type="checkbox" value="Life Insurance">&nbsp;&nbsp;&nbsp;<label>Commercial Insurance </label><input name="group2[]" type="checkbox" value="Commericial Insurance">

You just access each checkbox in the array to see if it's value is "On" if so, it's checked

$_POST['arrayname'][0] through $_POST['arrayname'][n]

I tried the following and got the same "Array" output.
<?php
if(isset($_POST['Submit'])) {

$cname=$_POST['cname'];
$cnumber=$_POST['cnumber'];
$btime=$_POST['btime'];
$group1=$_POST['group1'];
$group2=$_POST['group2'];
$caddress=$_POST['caddress'];
$agent=$_POST['agent'];

if (isset($_POST['group2'][0])){
echo "Homeowners Insurance&nbsp;";
}
elseif (isset($_POST['group2'][1])){
echo "Auto Insurance&nbsp;";
}
elseif (isset($_POST['group2'][2])){
echo "Life Insurance&nbsp;";
}
elseif (isset($_POST['group2'][3])){
echo "Commericial Insurance&nbsp;";
}
else{
echo "Please Select Insurance Type<br />";
}

Hi intear,

With checkboxes, a value only appears in the array if it is ticked. If left unticked it won't be in the array. You should loop through the array, and build a string based on the ticked values.

Replace your line 8 with the following:

$group2 = "";
foreach ($_POST['group2'] as $key => $value) {
    $group2 .= $value . " | ";
}

I changed line 39 to this ( ."Insurance Type : ".$group2[0]."\n".$group2[1]."\n".$group2[2]."\n".$group2[3]."\n"; ) and it worked great.

Thanks for your help.

If you add checkboxes to your form you'll need to edit your code - looping through the array is more robust and won't need changing. Imagine trying to run your code if you have 30 checkboxes !! Nightmare :(
